IMPROVEMENT IN TRUSSES.

TO ALL WHOM IT MAY CONCERN:

Be it'known that we, CHARLES A. JnFFsRIEs and E. F. OLDs', ot' Dexter, in the'county. f Washtenaw, and State ofMichigam'have invented certain new and usefulv Improvements in "lrusses; and we do hereby declare that the' following isV a full and complete description ofthe same, reference being Yto the accompanying drawings, making part of this specification, in whichi i Figure'l is! an edge view of the truss.

Like letters refer to likeparts in the dierent views presented. p

A, iig. 1, is a pad, which may be constructed of wood, rubber, eroi` any other suitable material, and may be either round or oval, as shown in the drawing. Around the face of the pad is sunk a groove, B, iig. 6, thus forming a central convexI projection, C, and anoutcr rim, D. i The purpose of thus constructing the face of the padis, that when it isapplieditnthe.rupturegthe c'entral projection will pressdirectly into the orifice of the rupture, and thereby'hold `that portion of the bowels which is inclined to escape, firmly within the abdomen, while, at the same time, the projecting rim on the outer-'edge of the4 face of the pad tends constantly to press the integuments under the pad toward the centre of the rupture, andthereby gradually produce a reduction of the size of the rupture, and ultimate adhesion oi its edges. In order to facilitate this adhesion, as fast asthe sine of' the rupture is reduced, by the constant pressure of `the outside rim toward the'centre ofthe rupture', portions of the central projection `of thevpa'd may be from time to time removed, or pads witha smaller centre may be appled,'unt1 the face'otthe pad becomes entirely concave, asshown in iig-.7, and thus rendered capa. ble ofA bringing-,the edges of therupture together, and holding them in contact until a permanent adhesion can take place,A Asa'bove said, the pad may .be ovnl,'oblong,`or round, or any shape that -best suits the case under .-treatment, and which is applied tothe injured part by being attached to a belt, E; 5g. 1, which is buckled around the body'. The pressnreof the pad upon thel rupture is regulated by the springs F, iaed tothe back ofthe pad, ahd whichrextend cach wayin direction of thevbelt, theends curving forward, so that when brought downby straps, the pressure can be regulated as desired. The springs are attached to the pad by means of the plate G, to which they are dared, andthe plate secured tothe-padby screws, thus givingto'its attachment great strength and security. .Toe'ach end of the springs are attached straps, which festen into buckles securedto 'thbeln so as 'to adjust the pressure of the springs'uponthe pad; hence, by means of these springs, straps,

and buckles, the direct'pressure'ot'the pad upon the rupture is not' only secured, but the inclination of the pad in any directio n is accomplished, by simply loosening the straps on one side, and tightening 'them on the oppo siteside. .For-,the purpose of varying the tension of either side oi the belt, `the straps und buckles at the end are fastened at the 'cuter edges of the belt; For a double herniaar iother pad may be attached to the belt, and applied ,as above described.

, H, iig. 4,(is a form of pad which we propose sometimes tense, insteail'of Vthe solid o`ne 'above described. This pad is provided with an adjustable-centre, C, g. i6,.which maylbe moved in .or out of' the 'pad by means of the central screw I, and thus'any degree of prominence may be given to the centre. The upper section, J, of the pad', is secured to the lower one by means-of the side-screws K, passing through the upper section-into the lower. The purposeof this larrangement is to facilitate, not only thevholding'of the bowelsin placeby` the central projection,` but the closingup of' the orifice, by means of pressing the parts toward the'centre'. As soon as it will answer to. raisethe central projection, it is easilydoe by the screw I, andthiis give a larger cavity to the face of lthe, pad, so that more of the iiitegumentswill pass under it w'lile.` this isbeing done. The outer rimrcan'be from time to,4 time letdown by the side-screws, so that it will press more irmly the parts together. We d'o not propose vto make all the pads-in this way; some of themwill have only one part movable, either theA central adjustable and the outer iiXed, or the central fixed and the outer adjustable. They are represented both movable in one pad, simply-for convenience, and not for practical use.

In the use of the solid pad, it is sometimes found necessary to ventilatol it, when the pressure is too much, in consequence'of the exclusion of the air from underthe pad. In order to do this easily and readily, apportion of the upper side of the' pad is' removed, making anv airchauiben-L, iig. 8. Through the'hottom of this chamber are bored. small holes, a, through which the air may find passage to the face of the pad. The top of this chamber is covered with a piece of--rnbber packing, M, on thc top of'which is fitted a metallic plate, N,

both of which arfe lscrewed into the recess or rabbet surrounding the top of 'the air-chamber, as shown in the' cross-section, gs. By this means the chamber is made air-tightat .the top, :tir being admitted to the chamber only by passing-down the side of the screw O, aportion of one Vside of -which is-cut-away, so that on screwing it, up to the section thus removed, air willpass down by the side into ythe-chamber, and' from there to the `face of the pad.- On driving the screw down, yso that the'uncut part ofthe screw will enter the hole, theair is thereby prevented'from entering the chamber, and, as a consequence, more willpass to the face ofthe pad. A By 'this simple device the pad can'be at all times ventilated, without disturbing its position and relation tothe rupture.

Fig. 8 is a form of' pad which maybe used 'for the leftor right side, byl simply turning the lower section, A', hg. 9, around, from one side to the otheigttbc'two sections being so pivot-cd to each other, that the central Aprojection, B', tig. 8,v always occupies the same distan-cc from the centre of' tho'belt, the turning only varying the Obliquity of the pad, and consequently the line of .the central Iprojection or core, instead oi carrying it around in a circle, and making itstiistance` fromvthe ,centre oi' the pad variable. It will be observed thatthe two screws ,whichrhcld cap or section- C of` the pad to| the belt, after passing through the cap and-belt, enter a'metallic segment, D", g. 8, upon which the pad movies around either way, and which is firmly held in its position by two segmental plates, E7, between which the segment slides as it is being turned around; also that the central pin or screw, F', by which the central projection is adjusted, acts as the .pivot on which the pad turns, and when .the padfs properly adjusted, it is secured thus by the attachment-screws a, by which the cap or upper section ot'v the pad is fastened to the belt, as before said.y

,'W hat we claim as -ouriimprovemenh anddesi'e to secure by Letters Patent, is

1. The pad provided with a rigid c entral projection, as arrangedin combination with the, springs F and 'i belt E, for thelpurpose andin the manner set forth.

. 2. 'The pad H, when constructed with a central adjustable projection or core, c, adjustingfscrews' I K, when arranged in combination withz the cap J', plate Gr, amd'springs E, in the manner as and for the purpose substantially as set forth.`

3. pad, when constructed with a central air-chamber, L, Ventilating-holes d, and plate N,- in combination with the screw O and spring F, when arranged in the manner as described and shown in'g. 7.

4.-'1he segment-slide D', segmental plates E', and section or cap C', when arranged and pivot'ed tothe section A', byan adjusting-screw, F', working in and operating'a central core, B,'so that when the'pad is`.turned around from one side to the other, the said central projection or corc'B will always occupy the same direction vfrom the centre of the belt, in the manner substantiallyl as described and..shown`in gs.- 8 `arid 9.
